摘要：

A layer of volcanic ash (4 cm maximum recorded thickness) is present at similar to 250 cm depth in littoral sediments of Golhisar Golu; a small intramontane lake in Southwest Turkey. The major-element glass chemistry, determined by electron microprobe, is characterised by a rhyolitic composition. Trace-element data, determined by solution inductively coupled plasma mass spectrometry (ICP-MS) match previously reported results for proximal pumice samples from Santorini and Crete. Feat immediately below the tephra deposit has yielded radiocarbon ages of 3330 +/- 70 yr BP and 3225 +/- 45 yr BP (calibrated age range 1749-1406 BC). (C) 1999 Elsevier Science B.V.
